Session 15: Direct dark matter detection: Technical Developments- 1
- Jeff martoff (Temple University)
DarkSide-20k is a 20 tonne fiducial mass liquid argon TPC that will perform an instrumental background-free search for WIMP dark matter. The TPC will be outfitted with more than 125,000 silicon photomultipliers (SiPM) grouped into 5210 single-channel, $25\ {\rm cm}^2$ photosensors that are sensitive to single photoelectrons. We will present the performance of the photosensor and associated...
The LUX-ZEPLIN (LZ) detector is a next generation dark matter detector that will use a 7 active tonne liquid xenon time projection chamber (LXe-TPC) to search for dark matter particles, among other rare phenomena. The LZ project was approved in 2014 to continue toward fabrication and is now in the construction phase. In this talk, I will give an update on the current status and schedule of the...
In many experiments searching for rare nuclear processes, like direct interactions of cold dark matter particles, an extremely low radioactive contamination level of the detector target and the surrounding materials has to be achieved. This is only possible after implementation of an extensive R&D program and careful material screening with appropriate devices. Selected ultra-sensitive...
